structural considerations for a bath

[Leofric]

doesn't need to be filled to the brim. If you are floating, you will displace your weight in water.

Don't think you got the point - the weight supported by the bath is not reduced unless water is displaced from the bath. So, the bath supports the weight of water and people in it.(which is why ARUP need to know the weight of the 2 people here - )

I suggest that you don't need to know the weight of the people, rather how fat they are - ie the volume of the people.

If say, one is a big fat momma, then her body will take up the space in the tub and so there will be less space for water. So the calculation can not be the mass of the people plus the mass of the water, because you don't know how much water will fit in along with said big fat momma. You need to know the volume of the people, then deduct this from the volume of the tub available for water (say up to the overflow) then work out how much water can fit in. Convert this back to kg and then work out the mass of the body by multiplying the volume of the bodies by average mass (1010 kg/m3) and factor in something for any greater than average additional fat or muscle. Plus rubber duck.

What happened to the joke when it started back in post 37

This is serious. The OP has not had a bath since the start of February, and has been off work for six months before that with worry and anxiety thinking about it.

Any constructive comments are welcome.
